1sna230005r0300 – rc55 marker horiz 31-40

Why Choose the TE Connectivity ENTRELEC RC55 1SNA230005R0300 Marker Card?

The TE Connectivity ENTRELEC 1SNA230005R0300 is a pre-printed RC55 terminal block marker card designed for clear and consistent identification of electrical terminals in control panels, switchgear and industrial automation systems. Part of the established ENTRELEC RC55 marking system, this white marker card features terminal numbers 31 to 40 repeated ten times in a horizontal orientation.

Designed to simplify panel wiring and terminal identification, the RC55 system provides ready-to-use pre-printed markers without requiring individual labels to be produced on site. The 1SNA230005R0300 provides 100 individual markers arranged as ten repeated sequences from 31 through 40, helping panel builders, machine builders and electrical engineers create consistent and easily readable terminal assemblies.

With 5 mm spacing, horizontal marking and durable polyamide construction, the RC55 is suitable for compatible industrial terminal block installations. Its UL 94V-2 flammability rating and compact format make it a practical identification accessory for professional electrical panels and automation equipment.
